Master Tailwind CSS with Cursor & Context7: Epic Guide

On June 4, 2025, at 1:51 PM AEST, I embarked on an exhilarating mission to transform a mundane T3 App landing page into a dazzling Tailwind CSS Feature Demo that would showcase the full might of Tailwind CSS v4. Using Cursor, Context7 MCP, and Claude Sonnet 4, I collaborated with AI to create a repository that's not just a demo but a testament to modern web development. The result, hosted at github.com/mingfangdev/context7-example, is a stunning collection of 3D transforms, advanced gradients, and interactive animations.

The Vision: A Showcase of Tailwind's Cutting-Edge Features

My goal was ambitious: take a basic T3 App page and rebuild it as a Tailwind CSS feature demo with three complex examples that highlight the framework's most advanced capabilities. I wanted to push Tailwind CSS v4 to its limits, showcasing 3D effects, modern gradients, and dynamic animations.

The Tech Stack: Powering Innovation

• Next.js 15: React framework with app router
• Tailwind CSS v4: Utility-first CSS framework with modern features
• TypeScript: Type-safe JavaScript
• React: Dynamic UI components
• Context7 MCP: Real-time access to Tailwind CSS documentation
• Claude Sonnet 4: AI assistant for generating code
• Cursor IDE: AI-powered editor

The Journey: From Prompt to Polished Repository

Step 1: The Initial Prompt

"help me rebuild the page in a tailwind css feature demo page. and make 3 complex example that show the capability of tailwind css."

Cursor proposed transforming the T3 App's basic landing page into a feature-rich demo with three showcase sections:

• 3D Transform Gallery: Interactive cards with 3D flips, floating animations, and shape morphing
• Advanced Gradient System: Conic, radial, and angled gradients with color interpolation modes
• Interactive Animation Playground: Complex keyframe animations with staggered effects

Step 2: Building the 3D Transform Gallery

The AI delivered a section featuring three interactive cards:

• 3D Card Flip: A card that rotates 180 degrees on hover
• Floating Animation: A card that hovers and scales with custom keyframes
• Morphing Shape: A card that transforms from rectangle to circle on hover

Key utilities used: perspective-[1000px], transform-3d, hover:rotate-y-180, backface-hidden

Step 3: Crafting the Advanced Gradient System

A grid comparing different gradient types:

• Conic Gradients: Circular gradients with bg-conic
• Radial Gradients: Positioned gradients with bg-radial-[at_25%_25%]
• Color Interpolation: Visual comparisons of srgb, hsl, oklab, and oklch modes
• Angled Gradients: Diagonal gradients with bg-linear-45

Step 4: Creating the Interactive Animation Playground

Four dynamic components:

• Bouncing Loader: Three dots with staggered animate-bounce effects
• Multi-Speed Rotation: Spinners with varying animation-duration
• Pulsing Hearts: Heart emojis with timed animate-pulse effects
• Interactive Showcase: A card combining multiple hover animations

How to Build Your Own Tailwind Masterpiece

1. Set Up Your Project:

npm create t3-app@latest

2. Copy and save the rules in the root level

• components.mdc
• global.mdc

3. Send the prompt in Agent Mode:

help me rebuild the page in a tailwind css feature demo page. and make 3 complex example that show the capability of tailwind css.

4. Enjoy and wait for the result!

The Result: A Show-Stopping Repository

The final repository delivers:

• 3D Transform Gallery: Cards that flip with rotate-y-180, float with custom animate-float keyframes
• Advanced Gradient System: Conic, radial, and interpolation mode comparisons
• Interactive Animation Playground: Staggered bounces, multi-speed spins, pulsing effects

Why This Is Amazing

• Context7 MCP's Precision: Real-time documentation access ensured perfect v4 syntax
• Cursor's Speed: Claude Sonnet 4 turned prompts into production-ready code in minutes
• Collaborative Problem-Solving: Tackled syntax errors, migrations, and integrations together
• Tutorial-Ready Documentation: Detailed markdown makes it easy for others to replicate

Built with: Next.js 15, Tailwind CSS v4, TypeScript, Context7 MCP, Claude Sonnet 4
